Application 'filed October 28, 1921. Serial No. 511,140.

Be it-knwn that I, JOSEPH 0.-CADIEUX,

a citizen of the United States-of America,

residing at Meriden, Connecticut, have in-' 6 vented anevy and useful Electric Vibrator, of which the following. is aspecifica tion.

. The malinobjct ofmy invention is to pro- .vide a simple, reliable construction which,

can be economicallymade and which will not get out of adjustment accidentally or through deterioration with time.

The invention is shown as applied to one type of bel]. It should be understood that the invention ig.aipplicable to other buZzer* or ringer movements.

, Figure 1 is a plan view ofa construction embodying the -improvements of my invem tioi1; u

Fig. 2 is a face view of the vibrator' proper; Fi 3 is a perspective view of the pring mein er;

Fig. 4 is a perspective vieW of the arma: tre; 1

Fig. 5 is a perspective viewof the armature supporting member;

Fig. 6 is a side view and partial section;

showmg the electrmagnt and method ospporting the stationary contat;

Fig; 7 is a perspective view of a bracke for supporting, the magnets; and

Fig. 8 1s a sectional view of the adj means for the armature.

In the form shovvn, the base 10 supports; a gong top 0;- bell1l in any suitable manner. The electromagnet is supported by a bracket 12, which is secuied to the base loy a screw 13. The lora1cket m'ay be slotted;as at 14, and provided with a lug 14: c'entered in the base 10, so as to act as a. pivot and permit the bracket and the partssupported by it to be adjusted by a swinging move ment to bring the parts into the desired position. The cores15, 15 of the 'magnet are riveted to thebracket 12 and carry a yoke 16 at their opposite ends.

for the coil windings and hold t em perm -nentl in their proper relative positions. 7

A may be screw has a 'threaded scat in the end 25 of This yoke, the ocre-a and the bracket 12 di0rm a ri (1 support .Whiclrthepins 18 of the armature 19 are pivoted. The armature may be provided with a hammer arm 20 when the mechanism' is used'as a. strikr or ringer for a bell. or the like. A non-metallic stop 21 56 provided Qn'the armature. to prevent said armature r0in sticking to the magnet ocre.

A sprir1g member 22 performs the doublefunction of a tehsioning device for the armature and also' the m'ovable member .of the make-and-break contact. One end is perforated at 23t0 allow forthe free passage 01 the shank of ari adjusting .sc1ew 24. 1he

the; jyoke 16,50 that,.by.rotating the screw. the end of the spring 22 may be flexed to provide the necessary tension for operation.

llhe screw may be provided with any suit-- able form of head 26.. In the back of the head of the screw is a series of recesses 27 adapted to receive bosses 28 formed on the nd of th spring 22. These recesses and bosses hold thescreW from accidentel rotation and yet permit the screw to loe turned 7 when ibis desired' to tighten or I00sen the jspring.

The opposite. end of the spring 22 is pro Vided W1th .3. contact 29, Which is adapted to--malke or breakthg circuit from the contact30,;which is carried by the arm 31 of the -yoke but insulated therefrom.

il t will be seen tlat the construction 13 such that it is impossible for the coils to pull apart. The construction of'the yokeand method of supporting the armature and spring aresuch as to keep the contact oints idproper aligmnent. It isalso possi le to adjust the action by means of the screw 24, instezd of by the use of pliers for bending springs, as is frequntly done in other constructions. B lo'osening the -screwl3 and V adjustih the racket 12 the ringinechanism ma be ocated on the base tOaccommodate a lar eror smller bell.

Icaimr .1. In; an electric whrator, an electromag .net, a ke carriedthereby, an armature piw otally carried by said yoke, a s ring member secured .to said.armature, an a 3ustmg screw passing through une end of s'aid spring and said ears, an arm connected to said yoke, a adjusbable in said yoke, and'a s tatiohary spring connected to said armature, a screw contact alsb carried by said yoke and coco-acting With one end of said spring and 1 i'tcting with the opposite end of said spring. With said yoke, and et contact carried by said 8 2. In an electric vibrator, a magnet, a yoke nrm, the opposite and of said spring co-actcan*ied' thereby and having ears integral ing with said contact. therewith, an armature pivqtally carried by JOSEPH O. CADIEUX.
